Implementation of a bank card number recognition system based on OpenCV (1)-steps for bank card number recognition

I. Introduction

When selecting the topic for the graduation project before, I wandered between two topics, one is the license plate recognition system, and the other is today’s themed bank card number recognition system. After thinking about it for a long time, I decided to make it, which will not only deepen the computer vision The understanding of this aspect will also consolidate the knowledge you have learned. Not much to say, let’s get to the topic, this article mainly introduces the steps of bank card number recognition.

Second, the steps of bank card number recognition

First, let me explain the general idea.
The method I used is a relatively simple template matching method. What is a template matching method? A detailed explanation will be given later.

• template
  

• First, we first process the template as follows

• Follow the steps below to process bank cards. The
